Abstract: Thermochromic compositions that include combinations of at least one color former and at least one Lewis acid in a polymer mixture are disclosed. The thermochromic compositions reversibly change appearance from substantially transparent to substantially non-transparent above a lower critical solution temperature.

Abstract: A method and a system is disclosed for affixing invisible or unobtrusive markings to mail pieces (4), and subsequently collecting information from the mail pieces for sorting purposes. The system includes the affixation of an optically contrasting layer (1) to a mail piece, the layer changing optically upon the application of a stimulus to present a contrasting background for imaging encoded information (3) applied over the layer and related to the mail piece.

Abstract: A method is disclosed for limiting temperature increase of a treatment area during photodynamic therapy (PDT), whereby temperature sensitive materials in the form of a skin patch or compound are applied over the treatment area. The temperature sensitive materials are optically changing from substantially transmissive to at least one of substantially scattering, absorbing or reflecting at wavelengths used for the PDT, the change occurring upon surpassing a predetermined temperature. In preferred embodiments, the optical changes are reversible as the temperature of the temperature sensitive compounds decrease below a predetermined temperature.

Abstract: This invention teaches a method for authenticating a document. The method includes the steps of: (a) providing a document to be authenticated; (b) illuminating at least a portion of the document with laser light that exceeds a threshold fluence; (c) detecting a narrow band laser-like emission of at least one wavelength from the document in response to the step of illuminating; and (d) declaring the document to be authentic only if the laser-like emission is detected.
